Subject: [PATCH 3.2 73/94] unicore32: add ioremap_nocache definition

3.2.62-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Guan Xuetao <gxt@...c.pku.edu.cn>

commit a50e4213e71adc7dde0d514aabd8af7275fee39f upstream.

Bugfix for following error messages:
lib/iomap.c: In function 'pci_iomap':
lib/iomap.c:274: error: implicit declaration of function 'ioremap_nocache'
lib/iomap.c:274: warning: return makes pointer from integer without a cast

Also see commit <f1ecc69838a2d7c8a3e1909f637d4083c071777d>
  it will hide the ioremap_nocache function for systems with an MMU
